Spectral lines

What are spectral lines and how can you use these to distinguish between elements
More background on spectral lines
How spectral lines relate to Bohr's model of the atom and how the electrons can be excited to jump to a new orbit.
How the spectral lines are made
part 1
part 2
Now use this information to explain how the flame test experiment can be used to explain why the different elements have different colours when heated.

Electron configuration

how to write electron configuration using spfd notation and why electrons are in pairs and how the shells fill up.
